Welcome to arraycontext’s documentation!

GPU arrays? Deferred-evaluation arrays? Just plain numpy arrays? You’d like your code to work with all of them? No problem! Comes with pre-made array context implementations for:

• numpy

• pyopencl

• pytato (for lazy/deferred evaluation)

• Debugging

• Profiling

arraycontext started life as an array abstraction for use with the meshmode unstrucuted discretization package.
